After the conquest of France in 1940, Germany felt the need for a mobile mount for their Wurfgerat 40 rockets, and the Sd.Kfz. 251 was selected. The resulting Sd.Kfz. 251 Wurfrahmen 40 had three rocket projectors mounted on each side of the halftrack's hull. Each of the launching frames could be traversed from +5 degrees to +40 degrees. This vehicle gave panzerpionier units a heavy bombardment capability. This comprehensive kit provides modelers with parts to load either the 32cm incendiary round or 28cm HE round rockets on their halftrack. There's a third choice, for modelers can also mount a 3.7cm PaK 36 anti-tank gun on the Sd.Kfz. 251. This latter variant was issued to platoon leaders so as to provide heavy support.
